West Springfield, Mass.,

Massachusetts a corporation of Application July 21, 1944, Serial No. 545,893 6 cs. (01. 222-74) This invention relates to improvements in liquid measuring and dispensing apparatus, such for example as is used for dispensing measured quantitles of gasoline or the like in service stations.

The invention has for its object to provide in an apparatus of the class described, a reel on which the dispensing hose is wound and which is bodily movable from a completely housed pocasing, where the hose may be unwound from the reel for servicing a car and subsequently rewound, when the servicing is completed.

. The invention has for another object to provide in the apparatus of the class described, a door in the casing of the apparatus, and a carriage, which carries a reel, or other form of hose a 9 i M liquid dispensing apparatus showing a modification of the invention.

Referring to these drawings and first to Fig. 1 thereof, the invention is shown, by way of illustrative example, as embodied in a gasoline dispensing apparatus of a form that is well known ".sition-inside the casing to;.a position outside the and. now currently used. Such apparatus includes a combined pump and air separator unit l, a suction pipe 2 for the pump, a discharge pipe 3 for air-free liquid leading from the separator to a m er a d r e conduit for the meter including rigid piping 5 and, as its terminal portion, a flexible hose 6 having on its delivery end a the usual valve-controlled nozzle I (shown in Fig.

4).- The apparatus also includes suitable registering means 8, driven by the meter 6 and indi- 1 eating the quantity and/or cost of the measured in apparatus of the class described, a valve in the dispensing conduit and means for opening and closing the valve by the opening and closing of the door or by the movement of the carriage out of and into the casing, respectively.

A further object of the invention is to provide in an apparatus of the class described, means for preventing resetting of the register when the hose reel, or other hose storage means is in servicing position outside the casing. I

The invention will be disclosed with reference to the accompanying drawings, in which- 4 Fig. 1 is a front elevational view, with parts in section and parts broken away, of a liquid dispensing apparatus embodying the invention;

Fig. 2 is a fragmentary front elevational view of the apparatus showing .the hose reel drawn out in position for use;

Fig. 3 is a sectional plan view taken on the line 3-3 of Fig. 1;

quantities of liquid dispensed. This apparatus is housed in a suitable casing, including sheet metal front and back walls 9 and I0, respectively, side walls II and I2 and a. top l3, together with a framework of four angle irons Hi, fixed to and upstanding from a base l5. The pump-separator unit I is supported by legs it from base l5. The pump is driven by an electric motor I6 supported from a side wall of unit I. The motor is provided with a switch which is contained within a box ii and which is operable by a lever l8, being closed and opened, as the lever is raised and lowered respectively. The register 8 .is supportedfrom a platform I9, 'iixedto the angle irons it. The

register is provided with suitable means for resetting it to zero. As herein shown,- such means includes a hand crank 20 fixed to a shaft 2!,

suitably mounted, as indicated, in the casing and framework of the apparatus.

The present invention provides a hose storage means, such as a reel, on which hose 5 is wound and which ismounted on a carriage that can be moved out of and into the pump casing to carry the reel into and out of operative position, as shown in Figs. 2 and 1 respectively. Also, the carriage is interlocked with the register-resetting means, such as shaft 2 i, so as to render the latter inoperable while the carriage is drawn out. The carriage is also interlocked with the switch of the pump motor so as to start and stop the latter, when the carriage is moved, into and out of Fig. 7 is a fragmentary cross sectional view operative position, respectively.

The carriage includes a pair of parallel rods 22,

(Figs. 3 and 4) mounted to slide in'bearings 23,

provided one near eac'hend of a supporting mem ber 2a, which spans the space between a pair of the angle irons i4 and is secured at its ends, one to each angle iron as indicated. The rods 22 are fixed at their inner ends to and interconnected by a cross member 25. The outer ends of rods 24 are fixed to a plate 26, to which is secured a sheet metal door 21 of the same cross sectional shape as the casing wall II. This wall is provided in upper and lower sections, spaced apart to receive between them the door 21. When the carriage is in its inner position, door 21 is closed. When the door is opened, the carriage is drawn out, as indicated in Fig. 2. A handle 28 is fixed to the outer wall of the door as a convenient means for moving it. The outward movement of the carriage is limited by the abutment of the ends of cross member 24, with the inner ends of the bearings 23.

The described carriagecarries a suitable hose storage means, in this case a reel 29. The plate 26 (Fig. has fixed thereto an inwardly extending spindle 30 which by means of a pair of ball bearings 3|, rotatably supports the reel. The reel is held in place axially on the. spindle between a shoulder 32 on the latter and a nut 33 on the threaded inner end of the spindle. The nut is located in a recess in the inner end face of the hub of the reel and this recess is closed by a plate .34, which together with a casting 35 and suitable gaskets 36, is clamped to the hub by bolts 31.

The casting 35 afiords within it a chamber 38 into which liquid may enter from a pipe 39 and from which liquid may leave by way of a passage 40. The pipe 39 is fixed at one end in the hollow central hub-4| of the above described cross member 25. The pipe 39 extends axially through the end wall of member 35 and into chamber 38 with its inner end in free communication at-all times with such chamber. The casing 35, revolving with the reel, turns on pipe 39 and a seal ring 42, mounted on and sealed to the pipe, is pressed by a spring 43, acting against a collar 44 on the pipe, against the inner ,face of the end wall of member 35 to avoid the chamber 38. A collar 45 on the pipe 39 engages the outer end wall of member 35 and holds the latter and the seal ring parts in their proper relative positions during assembly of member 35 on reel 29.

leakage from sequently, when the pull on the hose is relaxed, the spring 59 will turn the reel counterclockwise and wind up the hose. The winding up movement of the reel is limited in any suitable way, as by one of the flanges 55 (Fig. 4) on the nozzle 1 which will engage the nozzle-supporting clip 48. Figs. 4 and 6 are taken in opposite directions.

Accordingly, the winding up movement of the reel is clockwise in Fig. 4 instead of counterclockwise as in Fi 6.

Interposed in the discharge conduit 5 of the apparatus is a valve 56 (Figs. 1 and 3) having an actuating lever 51 with a. slot which receives a stud 58, fixed in the inner end of an extension 59 of one of the rods 2-2 of the carriage. When the carriage is positioned as in Fig. 1, the valve 56 is closed, and when door 21 is opened to draw out the hose reel into the position shown in Fig. 2, the valve is open. The flow through the discharge conduit may thus be controlled by the movement of door 21 and the hose reel and its carriage.

Movementof door 21 is also arranged to control the switch of the pump motor, closing and opening the switch as the door is respectively opened and closed. Referring to Figs. 3 and 7, a rod 60 is mountedto slide horizontally in a sleeve 6| formed on member 24. The bore of this sleeve (Fig.7) is divided by a partition 62 in which the rod slides. A spring 63, acting between the partition62 and a collar 64 fixed to rod 60; tends to move the rod outwardly. The door 21 in closing abuts the outer end of rod 60 and moves it inwardly, compressing spring 63. The inner end of rod 60 is pivotally connected to one arm of a bellcrank lever 65, which is pivotally mounted in a bracket 66, fixed by bolts 61 (Fig.

' 3), to a cross bar. 68, which spans the space be- The discharge conduit 5 of the meter 4 is connected, as indicated in Figs. 1 and 3, to the hollow hub 4| and thus to pipe 39. Such connection includes a flexible hose 46 of sufllcient length to enable the desired range of sliding movement of the carriage. The hose reel has a cored passage 41 (Fig. 5) which at its inner end is in communication, by means of registering holes in plate 34 and gaskets 36, with the outlet 4|! of chamber 38. This passage 41 extends radially outward and then turns and follows the periphery of the reel. The hose 6 at its inner end is connected, as indicated in Fig. 3, to such cored passage. The hose 6, as shown, is wound in several convolutions on reel 29 and its nozzle 1 is supported by a clip 48 (Figs. 4 and 5), fixed to the inner face of door 21 and by a lug '49 (Fig. 4) fixed on the plate 26 of the carriage.

The hose reel 29 (Fig. 5), in its face adjacent door 21, is provided with a recess to receive a spiral spring 50, which at one end (see also Fig.

6) is fastened to a pin 5| on late 26 and at the other end is fastened to a pin. 52 on the reel. A

- plate 53, fixed to the reel, as by screws 54, closes the spring recess in part and retains the spring in place. When the hose is pulled to unwind it tween, and is secured at its ends to, a pair of the described angle irons l4. The other arm of bellcrank 65 is connected by a link 69 (Fig. 7) to switch lever l8. With the parts positioned as shown in Figs. .3 and 7, the switch is open. When door 21 is opened sufliciently, the spring 63 will move rod 60 outwardly into the position shown by dotted lines in Fig. 7 until a collar 10 on the rod abuts the partition 62. the rod will serve to close the switch and start the pump motor.

From Fig. '7, it will be clear that the described movement of rod 60 cannot occur while'a vertical rod 1| has its lower end positioned as shown in the path of a-cylindrical part 12 of rod 60. This. rod 1|, the lower end of which is slidably mounted in an upturned sleeve 13 on member 6|, extends upwardly (Fig. 4:)v along the adjacent angle iron l4 to a point above the reel 29, where it turns inwardly to a point centrally of door 21 and then extends upwardly in a line radially of register reset shaft 2|. Therod 1| is suitably supported, as by a pair of bearings fixed to cross bars 15 which interconnect a pair of angle irons I 4 and are secured at their ends thereto. A collar 16, fixed to rod 1| near its upper end, is adapted by abutment with the upper face of the upperbearing 14 to limit the downward movement of rod 1|. A spring 11 on rod 12, acting between the lower face of the upper. bearing 14 and a collar 16 fixed on the rod, tends to hold rod 1| in the position shown in Figs. 4 and '1. when rod 1| is lifted, its upper end is adapted to engage in a notch 19in a disk fixed to reset shaft 2|.

Rod 1| is lifted manually as an incident to un-- locking door 21. As shown in Fig. 5, door 21 has This movement of 4 aeiaosr 'a lug 8i inturned from its upper edge, forming a striker plate which is perforated to receive the beveled lower end of a latch bolt 82. This bolt is of square cross section and is slidably mounted in a hole of similar cross section in a casing 83, fixed to upper section of wall H. A finger piece ti, fixed to the bolt, extends outside this section of wall 9 l for convenient actuation. Fixed on the upper end of bolt 82 are two spaced collars 85, the lower one of whichby abutment with the top of casing 83, limits the downward movement of the latch bolt and holds its beveled lower end at such a level that it can. be cammed upwardly by striker plate 81 on a closing movement of door 21.

An arm 86, fixed at its inner end to rod ll, has its outer end forked (Fig. 3) to straddle the bolt 82 and to lie between the collars 85 (Fig. 5). It will thus be seen that when'latch 82 is lifted by finger piece 84 to unlock door 21, the upper end of rod ll will be pushed upwardly into notch 19 (Fig. 4) and the lower end of the rod will be lifted out of the path of the part 12 (Fig. 7). Door 27 may then be pulled outwardly and, in so doing, rod 50 moves out to close the switch and the part 12 (Fig. 7) moves in under the lower end of rod -|l, thus holding rod H in notch 19 and preventing resetting of the register, while the door M is opened. In the act of closing door 21, the rod 60 will be engaged and moved to the left (Fig. 7) near the final closing movement of the door. When the door closes, member 72 will move to the left enough to allow rod H to drop,

whereby latch 42 will be forced into the hole in plate Bi by spring I1 and the upper end of the rod will be withdrawn from notch I9, enabling resetting of the register by crank 20.

It is not necessarily essential that all of the hose be wound up on reel 29. Some of it may be exposed outside the casing of the pump, if desired, as shown in Fig. 8. Here, the nozzle I is hung up on the upper section of wall H. as indicated, a notch 81 being provided in the lower edge of the upper section of wall II to receive the hose 6 when door 211s closed.

To prevent chafing oi the hose 6, the vertical side edges of door 21 may be rounded as indicated at 88 in Figs. 3 and 5.

In operation, the finger piece at is manually lifted to disengage-latch 82 from plate 3| and release the door. While finger piece at is held raised, door 21 is drawn out. This, as will be clear from Fig. 7 will allow rod Ell to be moved outwardly by its spring 53, thereby closing the motor switch and starting the pump in operation. Also, the part E2 of rod 60 will move in under the lower end of rod ll, thus maintaining latch M in its lifted position and also holding the upper end of rod ll engaged in the notch it in disk 8%, thus preventing actuation of the registerresettlng mechanism during a dispensing operation. As the door 2? is drawn out the valve 56 is automaticallyopened. With this valve opened and the pump in operation, the operator lifts nozzle i from its seat and walks toward the car to be served, unwinding so much of the hose 6 as he needs. The tank of the car is filledin the usual way-the operator controlling the flow by means of the valve in nozzle l. When the tank is suiiiciently filled, the operator relaxes his pull on the hose, whereupon the hose will be wound up on reel 29. The operator then places the nozzle in position and closes door 27. As the door nears its closed position, the motor switch is opened and valve 56 is closed. Finally, when the means preventing actuation of said resetting d door is fully closed, the part l2 of rod 60 releases rod ll, allowing it to drop between the parts 70 and 72 on rod 50, whereby to unlock shaft 2i and enable resetting of the register and to move bolt 82 into position to lock door 21. Incidentally member 12 prevents the motor switch from bein actuated until the rod II is again lifted and the door 2'! opened.

The invention thus provides a hose storage means that is normally completely housed within the pump casing and that can readily be projected outside the housing for convenience in servicing. The invention also provides for the interlocking of the motor switch, the dispensing conduit valve and the register-resetting means .'a casing for housing the aforesaid elements, a

door in said casing, a carriage connected to the door and mounted to move laterally into and out of the casing when the door is respectively closed and opened, means on said carriage forcarrying said hose, means for resetting said register, and

means while said door is open.
